It’s about to get a lot harder for white supremacist groups to fundraise and plan activities, as pressure grows on companies to kick hate groups off of their services.

Discover DFS, -0.26% is cutting ties with hate-group sites, the company said Wednesday, amid growing pressure on financial services to ensure white supremacist groups do not use their sites for funding. “Discover is committed to diversity and inclusion,” a spokesman told MarketWatch. “The intolerant and racist views of hate groups are inconsistent with our beliefs and practices.” Visa, the world’s largest processor of credit card payments, also stopped prohibited processing payments for hate groups, the New York Post reported. Apple Pay also told Buzzfeed it was terminating support for sites that sold white supremacist items and clothing Nazi memorabilia.

Earlier Wednesday, a spokesman for Mastercard said the company did not prohibit the acceptance of Mastercard-branded payments from merchants based on disagreement, but has since updated that statement. “We have reviewed a comprehensive list of websites provided by civic leaders and others,” he told MarketWatch. “We are shutting down the use of our cards on sites that we believe incite violence, as well as those who are wrongfully suggesting they accept our cards, when in fact they don’t.”

These moves come after PayPal PYPL, +1.01% announced Tuesday it would take extra measures in light of the events in Charlottesville, Va. last weekend to ensure its platform is not used to accept payments or donations related to hate, violence, or racial intolerance. “We are dedicated to providing financial services to people with a diversity of views and from all walks of life,” PayPal said in a statement. “While the challenges and the landscape are continually changing, we will continue to work hard to limit the efforts of those who try to use our services inappropriately.”

Earlier this week, GoDaddy removed neo-Nazi sympathizing website the Daily Stormer from its list of domains for slandering the 32-year-old woman killed at a white nationalist rally in Charlottesville on Saturday. The site had violated GoDaddy’s terms of service that prohibit “inciting violence against a group or an individual, GoDaddy chief executive officer Blake Irving said. Google later did the same to the site after it attempted to migrate there.

“We always have to ride the fence on making sure we are protecting a free and open internet,” Irving said. “And regardless of whether speech is hateful, bigoted, racist, ignorant, tasteless, in many cases we will still keep that content up because we don’t want to be a censor and First Amendment rights matter not just in speech but on the internet as well. But when the line gets crossed, and that speech starts to incite violence, then we have a responsibility to take that down.”
